A19350 - High Accuracy GMR Wheel Speed and Direction Sensor

General Description

The A19350 is a giant magnetoresistance (GMR) integrated circuit (IC) that provides a user-friendly two-wire solution for applications where speed and direction information is required.

Key Features

  • GMR technology integrates high sensitivity MR (magnetoresistive) sensor elements and high precision BiCMOS circuits on a single silicon integrated circuit, offering high accuracy, low magnetic field operation.
  • Integrated capacitor in a single overmolded miniature package provides greater EMC robustness.
  • SolidSpeed Digital Architecture supports advanced algorithms, maintaining performance in the presence of extreme system-level disturbances, including vibration immunit.
